Pretty difficult to find much difference in performance between the two. Factory power ratings for both vehicles are meaningless and difficult to find any non-patisan comparisons to provide any objective data to go by. I do remember seeing some years ago a show where they had a 'showdown' between 10 legendary cars of the era and the results were not conclusive. Basically the big hitters, the Hemi, the Boss and the Chevelle they had were all within the same range, any variations insignificant. no clear cut 'King of the Hill', so I think it really comes down to brand loyalty and personal taste in styling.
